# Choose Hiveku Mini, Max or Ultra

> Pick how capable, and how costly, the AI is for a builder chat or a workflow step

Hiveku's AI comes in three sizes. **Mini** is quick, and free in the website builder's chat. **Max** handles most work. **Ultra** thinks hardest, for big or tricky jobs, and costs the most credits. You choose the size in the builder chat and in a workflow's AI step.

This guide shows the choice in two places on Northwind's account: the website builder's chat and a workflow's AI step. Nothing was sent or saved.

## In the website builder

Open a website in the builder. Under the chat box, click the model name (here **Hiveku Max**) and pick one:

* **Hiveku Mini** (Free): fast edits and simple tasks, such as fixing a word or changing a color.
* **Hiveku Max** (\$): building a section, a new page, or a change across several files.
* **Hiveku Ultra** (\$\$): large changes that need careful thinking, such as reworking how a whole site is put together.

Your choice applies to the next message you send. Each answer ends with which size wrote it and, for Max and Ultra, what it cost.

In **Designer** mode, **Fast** and **Deep** beside it set how long the AI thinks: **Deep** gives the best design work, **Fast** gives quicker drafts. Design work in Designer mode is charged at the Max rate, whichever size you pick.

## In a workflow's AI step

Workflows can include an **AI Agent** step that writes or decides something as the workflow runs. Click the step to open its settings, then choose under **Model**. The **Model** setting shows when **Agent** is set to **None (direct model call)**. If the step runs as one of your agents, that agent uses its own model.

![Model, outlined: Hiveku Max picked; the list shows Hiveku Mini, fast responses for simple tasks; Hiveku Max, balanced reasoning for most workflows, ticked; Hiveku Ultra, deepest reasoning for complex tasks](https://mintcdn.com/locusdigital/naLblcUl0k_hqc-M/images/how-tos/ai-team/mdl-02-workflow-closeup.webp?fit=max\&auto=format\&n=naLblcUl0k_hqc-M\&q=85\&s=33bf15b482c44383ba67533a6b513482)

The step uses that model every time the workflow runs, so for a workflow that runs often, pick the smallest model that does the job well. Click **Save Workflow** to keep the choice.

Northwind only opened the setting to show it and left the workflow without saving.

## Which one to pick

* **Start small.** Try **Mini** for a small change. If the answer misses, ask again with **Max**.
* **Max is the everyday choice** for most building and most workflow steps.
* **Save Ultra** for jobs where a better first answer saves you several rounds.

## Good to know

* **In the builder chat, your plan decides which sizes you can pick.** See [AI Models](/ai/models). In a workflow's AI step every size uses credits each time it runs, Mini included.
* **Credits:** see how many you've used, and what happens when you run out, in [AI Credits](/settings/ai-credits).
